Explanation/Reference: Explanation: A low equal-error rate (EER) is a combination of a low false-rejection rate and a low false- acceptance rate. EER, expressed as a percentage, is a measure of the number of times that the false-rejection and false-acceptance rates are equal.

Estimated-error rate is nonexistent and therefore irrelevant.
